I am pretty confident that no Chinese chef has ever cooked the ingredients for a stir-fry in the oven. But I do not like frying aubergines: cubed ones, in particular, are reluctant to soften, and tend to stick to even well-seasoned pans. Once I had tossed my aubergines in oil, seasoned them, and put them in the oven, I realised that I did not need another pan for my other ingredients (leftover belly pork, cubed; sliced spring onions; chopped garlic). After 25 minutes, I threw them into the roasting tin with the aubergines, stirred them about with a little more oil (groundnut), turned down the oven (from gas mark 6/200C) to gas mark 2/150C, and gave everything a further 15 minutes.
Meanwhile, I cooked the rice (the link on the right takes you to various agonised posts on this subject), tipped it into the roasting tin, and mixed everything up with some soy sauce, nam pla, and rice vinegar. (There is a more detailed recipe, for another inauthentic pork stir fry, here.)
